Study Notes
- The symbol for the number of moles is "n."
- The unit for molar mass is g.mol-1.
- The equation that links moles (n), mass (W), and molar mass (M) is W = nM.
- The mass of 2 moles of carbon (Ar = 12) is 24 g.
- There are 0.25 mol in 10 g of calcium (Ar = 40).
- The molar mass (Mr) of water (H2O) is 18 g.mol-1 (Ar: H = 1, O = 16).
- A mass of 40 g of sodium hydroxide (NaOH) is needed to make 1 mole (Ar: Na = 23, O = 16, H = 1).
- There are 0.10 mol in 4.4g of CO2 (Ar: C=12, O=16).
- The equation that links density (d), mass (W), and volume (V) is W = dV.
- The typical units for density used in these calculations are g.cm-3 and kg.m-3.
- A liquid with a density of 0.8 g.cm-3 has a mass of 8 g in 10 cm3.
- A substance of 5g with a volume of 2.5cm^3 has a density of 2.0 g.cm-3.
- The rearrangement of W = dV to find d is d = W/V.
- The rearrangement of W = dV to find V is V = W/d.
- 2.00 moles of titanium has a mass of 95.8 g.
- One tonne equals 1,000,000 grams.
- 95.8g of Ti is 2.0 mol.
- The Ar/Mr of a substance is the mass of 1.0 moles.
- 2000g converts to 2.0 tonnes.
- 4.0 x10^-6 tonnes converts to 4.00 grams.
